The Battle of Brańsk, which took place on June 23, 1264, was a key event in the conflict between the Yotvingians and the Polish forces organized by Prince Bolesław V the Chaste. The Yotvingians, a tribe inhabiting the areas of present-day northeastern Poland, launched a raid into the Sandomierz region in early 1264, reaching as far as Tarczek in the Świętokrzyskie Mountains, where they caused significant damage and devastation. In response to these attacks, Bolesław the Chaste initiated a campaign aimed at defending Polish territories and spreading Christianity. The well-organized and disciplined Polish army reached Brańsk, where a fierce battle took place with the Yotvingians led by their chieftain Komat (Kumata). As a result of the clash, the Yotvingians were defeated, and their leader fell in battle. Legends say that a burial mound was erected for Komat, and the battlefield became known as Kumatowe Uroczysko. This battle not only had military significance but also cultural importance, symbolizing the struggle for the security and identity of the region. Historically, this conflict marked the future fates of both the Yotvingians and Poland, contributing to the consolidation of Christianity in the area. An interesting aspect is the local cult and traditions associated with this site, which attract tourists and historians, highlighting the rich history of the region and the influence of past events on today's communities.
